Learn Synthetic Biology in an engaging way: This school package explains the problem of antibiotic resistance and a way to tackle it using Synthetic Biology.The SYNPEPTIDE project presents an alternative approach to deal with the growing threat of multidrug-resistant bacteria: lantibiotics, a special type of antibiotics, come to help. The materials provided in the school package explain the structure of lantibiotics and another promising type of active substance, proteusin. Starting from the very beginning, the materials clarify the difference between bacteria and viruses as well as explain the structure and functions of amino acids, proteins, and different levels of their organization. In addition, an educational game Synmod, available for iOS and Android, introduces the topic of Synthetic Biology in a fun and engaging way. The game helps memorize the names and abbreviations of 20 common amino acids.The school package allows users to integrate the knowledge about amino acids and proteins with the application of this knowledge to tackle the problem of drug resistance.

This is a set of lecture notes for a course called "Introduction to Philosophy," focused on value theory (ethics, social and political philosophy, the good life, etc.). This particular course was centred on the questions: What is philosophy and what is its value? What have philosophers said about this, and what are some contemporary philosophers doing beyond teaching philosophy?

This video was recorded at SLONANO conference, Ljubljana 2007. Advanced Li-ion batteries providing enhanced storage capacities and improved power performances are currently required not only by the fast-growing market of portable electronics, but also by emerging electric or hybrid-electric vehicles. We are investigating two novel techniques for this purpose: Spark Discharge Generation (SDG) and Electrostatic Spray Reductive Precipitation (ESRP). SDG uses a physical "top down" approach that relies on the atomization of two metal rods via a sudden spark. Two cylindrical rods are connected to high voltage and parallel to a variable capacitance. The capacitors are periodically charged to the break-down voltage of the system determined by the gap between the rods. Through the high temperature of the generated spark, electrode material is rapidly evaporated, and the vapour condenses to form nano-sized metallic particles. In addition, an unconventional densification technique, called Magnetic Pulse Compaction (MPC), is being used for self-manufacturing metal or alloy rods to be atomized. ESRP is a physical-chemical technique relying on a combined "top-down" and "bottom-up" approach, which bridges aerosol generation with chemical precipitation in order to form nanoparticles. Electro-Spraying of liquids consists in the creation of charged aerosols by applying a high voltage between a nozzle, through which the liquid to be sprayed is fed, and a counter-electrode. Interesting properties of this phenomenon are the narrow size distribution of the emitted droplets, as well as tuning the droplet size by controlling experimental parameters. Moreover, high net surface charge on the generated droplets causes repulsive interaction, preventing droplet coalescence. These beneficial aspects have been exploited in combination with a well-known technique for the synthesis of metallic and alloyed particles, namely Reductive Precipitation (RP) of metal chlorides by NaBH4. Dissolved metal chlorides precursors are forced to flow by a syringe pump which provides a constant supply to the nozzle with a controlled flow rate. Under the influence of the high electric field small charged droplets are formed and attracted towards a ring-shaped counter electrode, which is placed in the reductive solution. In this way, the droplets containing precursor metal ions are driven into the reductive bath, where they are immediately reduced to their zero-valent state. Primary particles with size in the range of 2-5 nm can be obtained by proper selection of the experimental parameters.

This video was recorded at 7th International AAAI Conference on Weblogs and Social Media (ICWSM), Boston 2013. One's state of mind will influence her perception of the world and people within it. In this paper, we explore attitudes and behaviors toward online social media based on whether one is depressed or not.We conducted semistructured face-to-face interviews with 14 active Twitter users, half of whom were depressed and the other half non-depressed. Our results highlight key differences between the two groups in terms of perception towards online social media and behaviors within such systems. Non-depressed individuals perceived Twitter as an information consuming and sharing tool, while depressed individuals perceived it as a tool for social awareness and emotional interaction. We discuss several design implications for future social networks that could better accommodate users with depression and provide insights towards helping depressed users meet their needs through online social media.

This video was recorded at 7th International AAAI Conference on Weblogs and Social Media (ICWSM), Boston 2013. We investigate the structural patterns of the appearance and disappearance of links in dynamic knowledge networks. Human knowledge is nowadays increasingly created and curated online, in a collaborative and highly dynamic fashion. The knowledge thus created is interlinked in nature, and an important open task is to understand its temporal evolution. In this paper, we study the underlying mechanisms of changes in knowledge networks which are of structural nature, i.e., which are a direct result of a knowledge network's structure. Concretely, we ask whether the appearance and disappearance of interconnections between concepts (items of a knowledge base) can be predicted using information about the network formed by these interconnections. In contrast to related work on this problem, we take into account the disappearance of links in our study, to account for the fact that the evolution of collaborative knowledge bases includes a high proportion of removals and reverts. We perform an empirical study on the best-known and largest collaborative knowledge base, Wikipedia, and show that traditional indicators of structural change used in the link analysis literature can be classified into four classes, which we show to indicate growth, decay, stability and instability of links. We finally use these methods to identify the underlying reasons for individual additions and removals of knowledge links.

This video was recorded at 7th International AAAI Conference on Weblogs and Social Media (ICWSM), Boston 2013. Every day, users publish hundreds of millions of microblog postings in popular social-networking platforms such as Twitter and Facebook. When considered in aggregation, microblog postings have been shown to exhibit temporal patterns that reflect events of global significance. In this paper, we propose techniques to identify and quantify spatial patterns: for instance, a hashtag that is popular in one city on a given day, may become popular in a different city on the next day. Detecting these patterns is challenging given that the data are noisy and posts are not physically moving, i.e., they are not continuous trajectories in space like vehicles. Second, we introduce a multi-granular summarization model to describe the movement of a hashtag between two time periods. For interpretability, we seek representations of spatial changes that follow natural or administrative boundaries on a map, such as cities and states. We compare various movement measures using quantitative approaches and user surveys. We evaluate our movement summarization schemes by analytical loss and coverage functions. Our results show that it is possible to reliably detect relevant spatial changes automatically, and to produce simple summaries that represent accurately these changes.
